Surveillance of Time-varying Geometry Objects using a Multi-camera Active-vision System
… as self-occlusion. Herein, it is proposed that a multi-camera active-vision system, which dynamically selects camera poses in real-time, be used to improve TVG action sensing performance by selecting camera views on-line for near-optimal sensing-task performance. Active vision for TVG objects …

Second Story Television: Multi-Camera Sitcom Spaces, Objects, and the Suburban Spatial Imaginary
… of the suburban spatial imaginary with regard to multi-camera sitcoms from the 1990s. I contend that the physical flatness of the multi-camera set construction is tied to the ideological presentation of suburban life. Through a textual analysis of moments in these sitcoms, I explore how they …

Data Acquisition and Processing Pipeline for E-Scooter Tracking Using 3d Lidar and Multi-Camera Setup
… utilizing sensors such as monocular or stereo cameras, Light Detection and Ranging (LIDAR) sensors as well as Inertial Navigation systems (INS) systems. One relatively common method for solving DATMO and SLAM involves utilizing a 3D LIDAR with multiple monocular cameras in conjunction with an …

Design of a low-cost optical motion capture system using a multi-camera configuration and an asynchronous extended kalman filter
… a low-cost optical motion capture system using a multi-camera setup and a novel algo-rithm that embeds the camera model within an extended Kalman filter (EKF) for precise tracking of a robot's pose. The goal of this dissertation is to reduce the cost of an optical motion capture system by a factor …

A structure from motion photogrammetric method for continuously measuring and tracking the deformations of soils during triaxial testing
… files rapidly; (c) it is low cost. The whole multi-camera system costs only about $ 2K;(d) it can measure the complete 3-D deformations/strain distribution of the soil specimen; In addition to the triaxial test soil specimen measurement, a multi-camera-based method has also been developed to …

Sensor planning for novel view generation by camera networks
… from a set of independent networked robotic cameras. Specifically, the robotic cameras work to seek out texture and geometric information needed to generate the specified synthetic view or views, aiming to-with each successive camera move-increase confidence in the estimates of the pixel …

The prevailing theory is that the gait motion of the therapeutic horse provides sensory stimulus and movement patterns to the rider that mimic natural movements of healthy humans – patterns the patient is unable to produce. Nine …

Implementation of stereo correspondence algorithms for multi-baseline vision system
… this study is to determine the impact of varying camera baselines on correspondence and depth estimation. As the baseline increases the resolution of depth increases but finding correspondences is very tedious. On the other hand when cameras are placed close to each other and thereby reducing the …

Learning Consistent Visual Synthesis
… synthesis often requires a complex and expensive multi-camera setup. This is not practical for daily use because most people only have one cellphone camera. But a single camera, on the contrary, could not provide enough multi-view constraints to synthesize consistent visual content. Therefore, in …
